Sir Russel, tessa, crazygirluk, do you guys realise that what you're talking about as defined punishment (not acknowledging another person, silence etc) is the standard punsihment that most people mete out to people they're upset with in or out of bdsm play and relationships???? it's something most of us to to the people we love most in our lives - partners, kids, parents, friends .... and not even as a part of play!!!
